State which of the following are equations with a variable. In case of an equation with a variable, identify the variable.

(i) 17 + x = 5

(ii) 2b − 3 = 7

(iii) (y - 7) > 5

(iv) $\dfrac{9}{3} = 3$

(v) 7 × 3 − 19 = 2

(vi) 5 × 4 − 8 = 3t

(vii) 2p < 15

(viii) 7 = 11 × 5 − 12 × 4

(ix) $\dfrac{3}{2}q = 5$

(i) 17 + x = 5 is an equation with variable x.

(ii) 2b − 3 = 7 is an equation with variable b.

(iii) (y - 7) > 5 is not an equation (it is an inequality).

(iv) $\dfrac{9}{3} = 3$ is not an equation with variable.

(v) 7 × 3 − 19 = 2 is not an equation with a variable.

(vi) 5 × 4 − 8 = 3t is an equation with variable t.

(vii) 2p < 15 is not an equation (it is an inequality).

(viii) 7 = 11 × 5 − 12 × 4 is not an equation with a variable.

(ix) $\dfrac{3}{2}q = 5$ is an equation with variable q.
